Description
Technical Field
[0001] This utility model relates to the field of water meters, and in particular to an antifreeze water meter that can be quickly repaired. Background Technology
[0002] When performing rapid repairs on antifreeze water meters, a type of fast-repair antifreeze water meter is often used. This effectively avoids pipe freezing and damage caused by low temperatures, ensuring stable water supply and accurate metering under extreme weather conditions. Its modular design supports rapid disassembly and replacement of core components, significantly shortening downtime, reducing maintenance costs, and minimizing the impact on users' daily water use. Utilizing cold-resistant materials and an anti-icing structure, the water meter balances environmental adaptability and maintenance efficiency, solving the industry pain points of traditional water meters being prone to freezing and difficult to repair, while also meeting the demands of modern water management for efficient response and continuous operation.
[0003] Some existing quick-repair resistant water meter devices prevent freezing and cracking by isolating external low temperatures and balancing the water vapor pressure inside the meter. At the same time, the flow sensor accurately captures the water flow signal and transmits it to the data module to complete the metering. When metering abnormalities or component damage occur, there is no need to disassemble the entire water meter. Simply open the quick-release inspection cover on the outside of the meter body, quickly locate the faulty component with the help of the reserved cast iron base plate, replace the appropriate spare component, and close the inspection cast iron base plate to complete the repair. The entire process relies on modular design to greatly shorten downtime for maintenance, and the antifreeze structure can still maintain its original protective performance after maintenance.
[0004] In existing technologies, some antifreeze water meter devices that can be quickly repaired suffer from problems. When the water meter freezes, the internal water freezes into ice, which can easily crack the meter casing and cause leakage. To prevent the water meter from freezing and cracking, protective measures need to be taken for the water meter and pipeline. However, in reality, it is difficult to do a good job of protection in many fields or outdoor areas, which leads to the water meter freezing and cracking. After the water meter freezes and cracks, it needs to be returned to the factory for replacement, which is costly, time-consuming and complicated. Therefore, a fabric leveling device is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this application is to provide a quick-repair antifreeze water meter, which aims to improve the problem that some quick-repair devices for antifreeze water meters cannot perform quick repairs on the antifreeze water meters.
[0006] The present application provides a quick-repairable antifreeze water meter with the following technical solution: a quick-repairable antifreeze water meter includes a meter casing, a connecting pipe fixedly connected inside the meter casing, mounting plates fixedly connected to the left and right sides of the outside of the connecting pipe, a replacement mechanism installed at the bottom of the meter casing, a counting mechanism installed inside the meter casing, and multiple sealing rings fixedly connected to the left and right sides of the inside of the connecting pipe. The replacement mechanism includes a base, on the left and right sides of the base, multiple locking and limiting ports are provided, locking components are installed inside the multiple locking and limiting ports, and locking ports are fixedly connected to the outside of the locking components. A cast iron base plate is fixedly connected to the top of the base, a sealing base plate is fixedly connected to the top of the cast iron base plate, and the top of the base is fixedly connected to the bottom of the watch case.
[0007] Through the above technical solutions: by further improving antifreeze and maintenance efficiency, a self-expanding sealing strip can be added at the joint between the sealing base plate and the meter case. It automatically tightens and enhances the sealing performance when exposed to low temperatures. The locking component is optimized into an eccentric cam quick-lock structure, which can be quickly locked and released by hand. The surface of the cast iron base plate is treated with an anti-rust coating to extend its service life. After the water meter is damaged by freezing, the pipes do not need to be disassembled. The entire meter core can be replaced simply by releasing the bottom locking component, which greatly shortens the repair time and reduces maintenance costs.
[0008] Preferred; The counting mechanism includes a protective cover, a watch cover is fixedly connected to the outer right side of the protective cover, an adjustment component is installed inside the protective cover, an impeller a is rotatably connected to the inner bottom side of the adjustment component, an impeller box is fixedly connected to the inner bottom side of the protective cover, a filter screen is fixedly connected to the bottom of the impeller box, and the bottom of the protective cover is fixedly connected to the top of the watch case.
[0009] The above technical solution achieves non-contact, precise data acquisition by adjusting the impeller speed of the component, ensuring long-term stable counting without mechanical wear. The impeller box adopts an anti-siltation design, and its flow channel shape can guide the water flow to form a vortex, effectively reducing impurity adhesion. The filter screen has a detachable, quick-install structure for easy regular cleaning. An annular sealing ring is added between the protective cover and the cover to form a double sealing barrier.
[0010] Preferred; The locking assembly includes a locking bolt, a locking sleeve is fixedly connected to the outside of the locking bolt, the locking bolt is fixedly connected to the inside of a plurality of locking limit ports, the locking sleeve is fixedly connected to the inside of the mounting locking port, and the mounting locking port is fixedly connected to the left and right sides of the outside of the watch case.
[0011] Through the above technical solution: the locking bolts are precisely embedded in multiple locking limit holes, ensuring accurate and secure positioning and effectively preventing component displacement. The locking sleeve fits tightly with the installation locking hole, further enhancing connection stability and making the fixation of the left and right sides of the watch case more reliable. It can maintain structural integrity even under complex working conditions. When performing maintenance or replacement operations, the connection can be quickly disassembled by removing the locking bolts, greatly improving work efficiency.
[0012] Preferred; The adjustment assembly includes a meter head, a movement is rotatably connected to the bottom of the meter head, a sealing plate is fixedly connected to the bottom of the meter head, the bottom of the movement is rotatably connected to the top of the impeller a, the outside of the impeller a is rotatably connected to the inside of the impeller box, and the outside of the filter screen is fixedly connected to the bottom inside of the meter housing.
[0013] Through the above technical solution: In the adjustment component, the meter head and the movement are rotatably connected, and the angle can be flexibly adjusted with the sealing plate to improve the convenience of operation. The movement and impeller a are linked to accurately transmit the adjustment action to ensure stable water flow control. The impeller a rotates smoothly in the impeller box, reducing water flow resistance and improving adjustment efficiency. The filter screen is fixed at the bottom of the meter case to filter impurities, prevent the movement from jamming, and extend the life of the component.
[0014] Preferred; The cast iron base plate is externally fixedly connected to the inner bottom side of the watch case, and the sealing base plate is externally fixedly connected to the inner bottom side of the watch case.
[0015] The above technical solution uses a cast iron base plate as a rigid support frame, which is tightly fixed to the inner wall of the meter casing to ensure the overall structural stability of the water meter. This effectively resists pipeline stress and water hammer impact, and forms a reliable static seal with the inner wall of the meter casing. By separating the structural support from the functional seal, the long-term strength of the connection parts is guaranteed, and the risk of bottom leakage is eliminated, significantly improving the sealing reliability and service life of the water meter under complex working conditions.
[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. When the bottom of the water meter experiences expansion stress due to freezing at low temperatures, both components will crack first to absorb the stress and prevent it from being transmitted to the main body of the meter casing. This effectively protects the casing and significantly reduces the risk of damage to the water meter in low-temperature environments. In terms of maintenance, the locking component design simplifies the disassembly and installation process. The base and bottom plate components can be quickly disassembled by rotating the locking bolt. After cleaning, the components can be re-inserted into the locking hole and the bolts tightened to complete the replacement and installation.
[0017] 2. The built-in filter effectively removes impurities from the water, ensuring that the water entering the metering structure is clean. This reduces the risk of malfunctions caused by impurities clogging or wear of internal components, significantly improving reliability. The filtered water flows evenly and impacts the impeller, causing it to rotate smoothly. The impeller is then accurately converted into metering data by the mechanism, effectively ensuring the accuracy and stability of water measurement. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.
[0021] Example: A freeze-resistant water meter that can be quickly repaired, refer to Figures 1 to 3 The system includes a housing 1, which serves as the outer protective structure of the water meter, encapsulating internal components, isolating them from external environmental influences, and withstanding the water pressure within the pipes. A connecting pipe 2 is fixedly connected inside the housing 1, connecting to the internal water passage and guiding the water flow through the counting mechanism 5. It also provides an installation base for the replacement mechanism 4. Mounting plates 3 are fixedly connected to the left and right sides of the connecting pipe 2, serving as transitional components for connecting the water meter to external pipes, increasing the connection contact area, and improving the installation sealing. The bottom of the casing 1 is equipped with a replacement mechanism 4. When the water meter is frozen and cracked, the bottom plate will crack and protect the casing 1 from cracking. The cracked bottom plate can be replaced directly on site without recalling the original factory, which greatly reduces the maintenance cost after the water meter is frozen and cracked. The casing 1 is equipped with a counting mechanism 5. When the water flows through the connecting pipe 2, it will drive the impeller a54 to rotate. The speed of the impeller a54 is proportional to the water flow. The counting wheel on the movement 532 rotates accordingly and records the corresponding value. Multiple sealing rings 6 are fixedly connected to the left and right sides of the inside of the connecting pipe 2 to form a seal to prevent water from flowing through. The replacement mechanism 4 includes a base 41, which serves as the basic carrier of the replacement mechanism 4. The base 41 internally supports a cast iron base plate 45 and a sealing base plate 46. It can be quickly disassembled and assembled through a locking assembly 43. Multiple locking limit ports 42 are provided on the left and right sides of the base 41 to provide insertion and limiting channels for the locking bolts 431. Through cooperation with the locking sleeve 432, the base 41 and the watch case 1 can be quickly locked to ensure the stability of the connection. The locking assembly 43 is installed inside the multiple locking limit ports 42. The locking bolts 431 and the locking sleeve 432 cooperate to achieve quick locking and unlocking, which can be operated without special tools. The locking assembly 43 is externally fixedly connected to a locking port 44 and a locking sleeve 432, which provides an installation reference for the locking assembly 43 and ensures that the locking bolt 431 and the locking sleeve 432 are precisely aligned. The top of the base 41 is fixedly connected to a cast iron base plate 45, which serves as the mounting carrier for the sealing base plate 46, ensuring the reliability of the bottom seal and resisting the impact of water pressure on the sealing structure. The top of the cast iron base plate 45 is fixedly connected to a sealing base plate 46, which is installed on the top of the cast iron base plate 45 to isolate the water flow inside the case 1 from the base 41, preventing water from seeping into the base 41 and affecting the locking assembly 43. At the same time, it provides a sealing support for the bottom component of the counting mechanism 5. The top of the base 41 is fixedly connected to the bottom of the case 1. The counting mechanism 5 includes a protective cover 51, which is the outer protective housing of the counting mechanism 5, fixed to the top of the meter case 1, covering the adjustment component 53, and providing an installation reference for the meter cover 52. The meter cover 52 is fixedly connected to the outer right side of the protective cover 51, protecting the display area of the adjustment component 53 and preventing dust and water droplets from directly adhering to the surface of the meter head 531 and affecting the reading. The adjustment component 53 is installed inside the protective cover 51, which is the display and control core of the counting mechanism 5, and displays the cumulative water consumption through a mechanical pointer or electronic display screen. An impeller a54 is rotatably connected to the bottom of the adjusting component 53 and installed inside the impeller box 55. It rotates under the impact of water flow and drives the movement 532 through the main shaft, serving as the "power source" for measurement. The impeller box 55 is fixedly connected to the bottom of the protective cover 51, providing rotation space for the impeller a54 and guiding the water flow to impact the impeller a54 evenly, avoiding water flow turbulence that could cause the impeller a54 to rotate unstably. A filter screen 56 is fixedly connected to the bottom of the impeller box 55, filtering out mud, sand, and impurities in the water, preventing impurities from entering the impeller a54 and the movement 532 and causing jamming or wear, while also supporting the impeller box 55 to ensure accurate positioning. The bottom of the protective cover 51 is fixedly connected to the top of the case 1. Specifically, water flows through the connecting pipe 2, driving the impeller a54 to rotate. Its rotation speed is proportional to the water flow rate. The rotation of the impeller a54 is transmitted to the mechanism 532 through the main shaft, driving the counting wheel to rotate, thereby accumulating the water consumption and displaying it through the meter head 531. The water flowing through the impeller a54 is finally discharged through the base 41. The filter screen 56 filters the incoming water to prevent impurities from damaging the internal mechanism 532. When the water meter cracks due to freezing, the damaged base 41, along with the cast iron base plate 45 and the sealing base plate 46 on it, can be quickly removed from the meter case 1 and replaced by operating the locking component 43, restoring the water meter function.
[0022] Reference Figures 2 to 3 The locking assembly 43 includes a locking bolt 431, which is inserted into the locking limit port 42 and the locking sleeve 432. Locking is achieved through a threaded or snap-fit structure. The locking bolt 431 is externally fixedly connected to the locking sleeve 432, which is fixed inside the mounting locking port 44 and threadedly engaged with the locking bolt 431 to fasten the base 41 to the watch case 1, ensuring the sealing and stability after connection. The locking bolt 431 is externally fixedly connected to the inside of multiple locking limit ports 42, and the locking sleeve 432 is externally fixedly connected to the inside of the mounting locking port 44. The mounting locking port 44 is externally fixedly connected to the left and right sides of the watch case 1. The adjustment assembly 53 includes a meter head 531, which provides rotational support for the movement 532 and protects the movement 532 from water flow impact and low temperature. The bottom of the meter head 531 is rotatably connected to the movement 532, which converts the rotational motion of the impeller a54 into metering data to achieve accurate measurement of water flow volume. A sealing plate 533 is fixedly connected to the bottom of the meter head 531 and installed at the bottom of the meter head 531 to isolate the inside of the meter head 531 from the water flow area of the watch case 1, preventing water vapor from seeping into the meter head 531 and affecting the normal operation of the movement 532. At the same time, it provides sealing support for the main shaft of the movement 532 to ensure waterproof sealing performance. The bottom of the movement 532 is rotatably connected to the top of the impeller a54, the outside of the impeller a54 is rotatably connected to the inside of the impeller box 55, and the outside of the filter screen 56 is fixedly connected to the inside bottom side of the watch case 1. The cast iron base plate 45 is externally fixedly connected to the inner bottom side of the watch case 1, and the sealing base plate 46 is externally fixedly connected to the inner bottom side of the watch case 1.
[0023] Specifically, water flows through the connecting pipe 2 into the meter case 1, driving the impeller a54 to rotate inside the impeller box 55. The rotation of the impeller a54 is transmitted to the movement 532 through the shaft at its top, driving the counting mechanism 5 to work. The water consumption is finally displayed on the meter head 531. The water flowing through the impeller a54 is discharged through the cast iron base plate 45 and the sealing base plate 46 area at the bottom. During this process, the filter screen 56 filters the incoming water to prevent impurities from entering, and the sealing plate 533 isolates the water flow from water vapor, protecting the movement 532 inside the meter head 531. When the bottom base plate of the water meter cracks due to freezing, the base 41, including the base plate, can be quickly removed and replaced by rotating the locking bolt 431 to disengage it from the locking sleeve 432.
[0024] The implementation principle of this application embodiment is as follows: Water flows into the inside of the meter casing 1 through the external pipe and is guided by the connecting pipe 2 to drive the impeller a54 of the counting mechanism 5 to rotate. The speed of the impeller a54 is proportional to the water flow rate, which drives the counting wheel to rotate and record the flow rate value. When the water meter cracks at the bottom due to freezing at low temperature, the cast iron base plate 45 and the sealing base plate 46 of the replacement mechanism 4 crack first to protect the main body of the meter casing 1 from damage. During maintenance, by operating the locking component 43, the locking bolt 431 is released from the locking limit port 42 and the locking sleeve 432, and the base 41 can be removed. Then, the cracked cast iron base plate 45 and the sealing base plate 46 are directly replaced. After the repair is completed, the base 41 is reinstalled and locked, realizing rapid on-site maintenance.
[0025] After the water flows into the meter housing 1, it is first filtered by the filter screen 56 to remove impurities. Then, the purified water flows into the impeller box 55, which evenly impacts the impeller a54 to make it rotate. The rotation of the impeller a54 is transmitted to the movement 532 through the main shaft. The movement 532 converts the rotation information into metering data. Finally, the cumulative water consumption is displayed by the mechanical pointer on the display device on the meter head 531 for the user to read.
[0026] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
